STM32F412xE/G

Functional overview

A comprehensive set of power-saving mode allows to design low-power applications.

When the internal reset is OFF, the following integrated features are no longer supported:

•

The integrated power-on reset (POR) / power-down reset (PDR) circuitry is disabled.

•

The brownout reset (BOR) circuitry must be disabled.

•

The embedded programmable voltage detector (PVD) is disabled.

•

VBAT functionality is no more available and VBAT pin should be connected to VDD.

Voltage regulator

The regulator has three operating modes:

–

Main regulator mode (MR)

–

Low power regulator (LPR)

–

Power-down

3.19.1

Regulator ON

On packages embedding the BYPASS_REG pin, the regulator is enabled by holding

BYPASS_REG low. The WLCSP64 is available in two versions, one with the regulator

internally enabled and one with the regulator internally disabled. On all other packages, the

regulator is always enabled.
